Problems solved by technology

[0013] The existing coal-fired combustion-supporting sulfur-fixing agent is usually a powder, which is inconvenient to add, the coal-saving effect is unstable, and the dosage is very large
The coal saving rate is low. When the cement kiln or boiler process conditions change, or the coal quality changes, the coal saving rate will be further reduced

preparation example Construction

[0066] The preparation method of the coal-burning combustion-supporting sulfur-fixing agent provided by the invention is as follows: mixing all the raw materials together and stirring evenly.

[0067] The second aspect of the present invention provides an application of the above-mentioned coal-burning combustion-supporting sulfur-fixing agent in the electric power industry, petrochemical industry, and cement industry.

[0068] The cement industry is a resource-intensive industry that consumes a lot of energy and ore resources. my country's comprehensive energy consumption per ton of cement is still far behind the world level. Coal is the main fuel for the cement industry, and its supply is directly related to the cost of cement production. .

[0069] The production of cement uses limestone, siliceous and iron materials as the main raw materials. After crushing, batching and grinding, raw materials are made into raw materials. After the clinker is fed into the cement kiln and t...

Abstract

The invention discloses a fuel coal combustion-supporting sulfur fixing agent which is prepared from the following components in parts by weight: 2 to 6 parts of nitrate, 10 to 15 parts of ferrocenium tetrafluoroborate, 0 to 3 parts of industrial edible salt, 2 to 6 parts of calcium glycinate, 2 to 4 parts of a sulfur fixing agent, 0.5 to 2 parts of carboxylate, 6 to 8 parts of a surfactant and 100 parts of water.

Description

technical field [0001] The invention relates to the field of energy saving and emission reduction, in particular to a coal-burning combustion-supporting sulfur-fixing agent. Background technique [0002] China's energy production and energy consumption are dominated by coal. Coal is China's main energy source, and its reserves account for 90% of energy. Oil and natural gas are relatively small, and China's coal reserves are very rich. Moreover, there are many coal-forming periods, wide distribution, complex types, great differences in coal content, coal quality and development conditions, and the distribution of reserves is not balanced. [0003] The cement industry basically uses coal powder as fuel. The combustion of coal is the contact between the combustible organic molecules in the coal and the oxygen molecules in the air. Under the conditions of certain temperature and oxygen concentration, intense oxidation reaction occurs, accompanied by the release of A phenomenon ...
